When you think of supertalls you probably think of pricey real estate—not leafy parks in the sky. A new 1000-foot tower going up in Manhattan provides a more interesting take: Hanging gardens that twirl down the exterior of the building like a giant green exclamation point marking the end of the High Line.

The Spiral will be tall—about as tall as the supertalls along a strip of 57th Street nicknamed Millionaire’s Row—but the big difference here is that this tower is being built for office and retail space only. And from what Danish architect Bjarke Ingels told the Architect’s Newspaper, it sounds like an exceptionally nice place to work:

Designed for the people that occupy it, The Spiral ensures that every floor of the tower opens up to the outdoors creating hanging gardens and cascading atria that connect the open floor plates from the ground floor to the summit into a single uninterrupted work space. The string of terraces wrapping around the building expand the daily life of the tenants to the outside air and light.

Ingels has a thing for incorporating green infrastructure into his developments, like this almost-finished residential pyramid on 57th Street which hides a courtyard inside its walls. And he’s thinking about bigger issues around energy and sustainability; he’s designed two power plants which also function as community space. If anyone could design a socially responsible supertall, Ingels would be a very good candidate. Let’s hope the building’s agenda is as progressive as its appearance.
